摘要
贝尔凹陷地下水属于低矿化度的NaHCO3型水,含有较高的可溶气态烃、酚、脂肪酸等有机组分和溴、硼等微量元素。它们随着地下水的运动方向呈现有规律的变化,已发现的2个油田,有明显的水化学异常存在。从已知推未知,预测凹陷的含油气远景,为油气勘探开发提供了水文地球化学依据。
The underground water type of Beier depression is NaHCO3 with low salinity.The water contains many organic compounds such as soluble gaseous hydrocarbon,phenol and fat acid and Br,B and other trace elements.These organic compounds change regularly in the flowing direction of the underground water.The characteristics of water chemistry are obvious abnormal in two discovered oilfields.The data obtained provide a hydrogeochemical basis for the exploration and development of reservoirs through the prediction of hydrocarbon potential in the depression.
